本文对柑桔锈螨Phyllocoptruta oleivora(Ashm)(柑桔锈壁虱)实验种群的生态学特性进行研究,结果表明:温度、日照、营养条件对柑桔锈螨生长发育有很大影响。各螨态发育起点温度在13℃左右,世代发育积温为330.07日度,最适温度为23—32℃,最适日照长度为12±0.5小时。取食果实时对该螨生长发育和繁殖最有利,其次是当年生春梢。老叶及被害叶由于营养条件恶化,对其生长发育不利。文中还计算出该螨的种群增长趋势指数(Ⅰ)和内禀增殖力(r_m)。 In this paper, the ecological characteristics of Phyllocoptruta oleivora (Ashm) citrus experimental population were studied. The results showed that temperature, sunshine and nutrient conditions had a great influence on the growth and development of citrus rust mites. The development temperature of each mite state start at about 13 ℃, generation development accumulated temperature of 330.7 days, the optimum temperature of 23-32 ℃, the optimal sunshine duration of 12 ± 0.5 hours. Take the fruit on the mite growth and reproduction of the most favorable, followed by annual spring shoots. Old leaves and victim leaves due to deterioration of nutritional conditions, their growth and development adversely. In addition, the population growth trend index (I) and intrinsic fertility (r_m) of the mite were also calculated.
